I Owa-tonna, in the county of Steele and ,State of. Minnesota, have invented certainlnew and useful Improvements in. Driving, Means tor Churns, of whichthe following; is.- aspecifie cation.

My invention. relates to driving means for churns and. has for itsobject to provide a simple and efiicient transmission which: will be positive-inaction and shall provide means for rotating the churn drum at a plurality of. speeds and for rotating the central roller therein in opposite directions to: that. 01%- the drum.-

This application is a division of my (20-- pending application Serial Number 181,112,;

filedAugust-QS, 1913 The full. objects and advantages of my invention will appear in connection With the detailed description thereof and are par-tic ularly pointed out in the claims In the drawings, illustrating the: applica-fi tion oh my invention. in one form',- iguzre 1. is a perspective elevation view of the churn driving mechanism Fig. 2 is a plan View of: the parts shown in Fig; 1. Fig; 3 is a sectional end elevation With some parts broken: away. Fig. is a. detail sectional view ofione'of the boxes. 7

- The driving means: herein illustrated are shown as applied to a-cylindrical churn 10- carried on trunnions journa'led in bearings 11 formed on: standards 12, the trunnionsbeinghollow and having a shaft 13 extended through the same, a rotary beater 1% being mounted on the-shaft 13 within the-drum 10.- It will be apparent, therefore, that there are provided'two rotatable members, 10' and- 14,

' one Within the other, and the driving mechanism herein described provides means for differentially and independently rotating: these. two members.

The driving mechanism and the standards 12, above referred to, are supported upon legs 15, upon which are secured rods 16, 17.

Upon these rods are arched brackets 18, 19, the: standard 12' being mounted: upon the bracket 18. An upright standard or bracket 20 is also secured to rod 16, and these members provide the means for supporting the several parts of the driving mechanism.

J ournaled in bearings 21 and 22 on arched brackets 18 and 19 is amain driving, shatt- 23 having thereon a pulley 2% by which: the same may be operated from any desired source of power. As clearlyshown in: Figs. 2' and 4,; the bearings: 21 and 22'- areadjust ably mounted; being secured to brackets 18 and 19,, respectively, by means of bolts 26 upright 12 ,?as best shown in Fig, 3. These" setbo'lts are at theback-ofi the'bearing, boxes so as to receive the: force of the: pull: upon the shaft through the sprocket chains of the transmission. The outside box- 21: is provided with an additional. set bolt for steadying, the boxagainst the forward strain coming; from the: pulley 24. By means of these ,setbolts the entire shaft 233M161 the" parts carried thereby may be adj usted. bodily Y to the desired extent, thereby tightening. the various sprocket chains: which: run into: the shaft and Whichwill be hereinafter de' scribeds;

The: churn or cylinder 10,;that is the outer driven element, is driven from a counter sha-ft3'4sjournaled in bearings on brackets 18 and 19-parallel: with drive-shaft 23. Gounter shaft 341 has fast thereon a sprocket Wheel 35 from which: runsa sprocket chair-r 36-to-a large sprocket wheel 37' fast on the: end of drumz10. Loose on: shaft 34 are two: sprocket Wheels 38 and 39, respectively, of unequal diameter; The larger sprocket Wheel 39 is connected by means of a sprocketchain: 40 with a sprocket Wheel 41 tasoon; drivesha-ft 23, and sprocket Wheel 38 is con mated by a sprocket chain ea with: a

sprocket wheel 43 fast on: drive shaft: 23. V The: sprocket Wheels E1 and 43 may be ofi the'zsame' diameters It Will be apparent,

therefore, th atthe sprocket Wheels. 38 and 39 loo face of said clutch being adaptedto engage I i With a clutch face 45 on the hub of sprocket wheel 38 while the other face of clutch 44 is adapted to engage with a clutch face 46 on the hub of sprocket wheel 39. The clutch44 at high speed. hen the engagement of clutch 44 is with clutch face 46 the drum will be driven at relatively low speed lVhen the clutch 44 is in neutral position between the clutch faces 45 and 46 the drum will be stationary. The drive in each case is through the sprocket chain 36 and over the sprocket wheel 37 as illustrated in Figs. 1 and 2. To prevent back lash I have provided a tightener member cooperating with sprocket chain 36. as described and claimed in the said copending application, which comprises an arm 48 engaging roller 49 and spring 50. r

The central roller 14 above described is provided on its shaft 13 with a sprocket wheel 51 over which runs a sprocket chain 52, which sprocket chain runs over an idler sprocket 53 adjustably mounted upon the lug 15, as clearly shown in Fig. 3. A

' sprocket wheel 54 is loose on shaft 23 and has the hub thereof provided with a clutch I face 55 adapted to engage with a complemental clutch face on the hub of the sprocket 41 fast on shaft 23. The sprocket 54 is controlled by clutch lever 60. As shown in Fig. 3, the sprocket chain 52 engages the sprocket wheel 54 with oneof its runs. When thesprocket wheel is slid along shaft 23 so as to bring the clutch 55 into inoperative position said run of chain 52 will be displaced somewhat sidewise, but under such conditions the chain will be stationary. When the clutch is moved into its operatlve position, where it engages the clutch face on the hub of sprocket 41, the run of the sprocket chain 52, which meshes with the sprocket wheel 54, will be heldin proper alinement with the other run and the chain will be driven so as to rotate sprocket wheel 51 and roller 14 on shaft 13 in a direction opposite to that in which the churn or drum is being rotated.

The simplicity and efficiency of my transmission and driving mechanism will be apparent. All parts are exposed so as to be readily available for lubrication, cleaning or repair. Easily accessible means are provided for adjusting the parts so as to tighten the driving chains. The double-speed drive for the churn is very desirable and under perfect control, and the central roller is adapted tobe held stationary or driven re-' versely to the drive of the drum, as desired.

shaft and a sprocket wheel loose on the drive shaft, means connected with said loose sprocket wheel for rotating theinner mem' her, a counter shaft, means connected with said counter shaft for rotating the outer member in the opposite direction to the inner member, two sprocket wheels of unequal sizes loose on said counter shaft having drive ing connections respectively to the two fast sprockets on the drive shaft, means for con necting the loose sprocket'wheel on the drive shaft to rotate with the drive shaft at will, and means for connecting the counter shaft" to rotate with either 'of the loose sprocket wheels thereon at will. r

2. Driving mechanism for rotary members, comprising a supporting frame work, a drive shaft and a counter shaft mounted. in parallel relation on said 'frameworl -a two-speed sprocket chain transmission, on"

said drive shaft through the counter shaft to the rotary member,bearingboxes forsaiddrive shaft slidably mounted upon the supporting framework, set bolts at the back ofeach of said bearing boxes for moving the same to tighten the sprocket chain, a pulley f on the end of the drive shaft, and a set bolt at the outside of the box adjacent said pul f ley for holding the driveshaft r verse action by the pulley.

*3. Driving mechanism one within the other driven to rotate in relafor two members tively different manners, comprising a drive shaft and a counter shaft mounted in parallel relation, means under the control of the operator for effecting direct driving connection between the drive shaft and one rotary member, means for driving the other rotary memberfrom'said counter shaft, a pair of gears fast on the drive shaft, a pair of gears of unequal sizes loose on the counter shaft, 7

sprocket chains connecting said respective sets of gears, and means for connecting said:

counter shaft to rotate with either of said g 1 loose gears at will.

In testimony whereof I aflix my signature in presence of two witnesses.
